This article proposes a novel simulation approach that combines implicitintegration with the Bonded Discrete Element Method (BDEM) toachieve faster, more stable, and more accurate fracture simulation. Thenew method leverages the efficiency of implicit schemes in dynamic simulationand the versatility of BDEM in fracture modeling. Specifically, anoptimization-based integrator for BDEM is introduced and combined witha manifold optimization approach to accelerate the solution process ofthe quaternion-constrained system. Our comparative experiments indicatethat our method offers better scale consistency and more realistic collisioneffects than finite element method and material point method fragmentation approaches. Additionally, our method achieves a computationalspeedup of 2.1 to 9.8 times over explicit BDEM methods.
